What type of hose?

Since it looks like the brick just sits atop the concrete, it would be possible to drill a hole though the concrete, and tunnel a path to connect the system to the water.

Why? The first thing I would do is find out where the supply for the hose bibb is routed. There is likely no city in this country that would allow a permanently connected constant pressure valve being fed from a hose bibb in this manner. Around these parts as it currently is installed, there are numerous code violations.

That would be something like step two, assuming there is any practical access. I've seen some real horror shows fed from hydrants like these. Step one, of course, is to have a proper backflow prevention assembly in place, with plumbing no one will trip over.

I won't assume practical access exists. So many of these goofy installs are avoiding spending thousand(s) to source the water more directly.

You shouldn't assume anything. The water doesn't magically appear at the hose bibb. Get the plans, find the routing of the supply, assess your options. Personally, I wouldn't touch that setup with your hands and if I were ArTurf, I wouldn't be walking, but running to rip that out.
